Linux refers to the family of Unix-like computer operating systems using the Linux kernel. Linux can be installed on a wide variety of computer hardware, ranging from mobile phones, tablet computers, routers, and video game consoles, to mainframes and supercomputers. Linux is a leading server operating system, and runs the 10 fastest supercomputers in the world.

The development of Linux is one of the most prominent examples of free and open source software collaboration; typically all the underlying source code can be used, freely modified, and redistributed, both commercially and non-commercially, by anyone under licenses such as the GNU General Public License. Typically Linux is packaged in a format known as a Linux distribution for desktop and server use. Some popular mainstream Linux distributions include Debian (and its derivatives such as Ubuntu), Fedora and openSUSE. Linux distributions include the Linux kernel and supporting utilities and libraries to fulfill the distribution's intended use.

Mainline

Mainline tree is maintained by Linus Torvalds. It's the tree where all new features are introduced and where all the exciting new development happens. New mainline kernels are released every 2-3 months.

Stable

After each mainline kernel is released, it is considered 'stable.' Any bug fixes for a stable kernel are backported from the mainline tree and applied by a designated stable kernel maintainer. There are usually only a few bugfix kernel releases until next mainline kernel becomes available -- unless it is designated a 'longterm maintenance kernel.' Stable kernel updates are released on as-needed basis, usually once a week.

Longterm

There are usually several 'longterm maintenance' kernel releases provided for the purposes of backporting bugfixes for older kernel trees. Only important bugfixes are applied to such kernels and they don't usually see very frequent releases, especially for older trees.

I just finished my first assignment for a course on Advanced Operating Systems. And I decided to document my approach for building the Linux kernel from source and implementing my own system call.

There are a number of blogs that already tell you how to go about doing this, but some of them are outdated, and some seem unnecessarily complicated. My goal is to present a straightforward approach for doing this, which should hopefully help you save a lot of time.

Compiling the Linux Kernel from source can seem like a daunting task, even to someone who’s pretty comfortable with computers in general. It can also get really irritating if you aren’t following the right instructions.

So, here’s a guide to help you through the process of building the kernel from source, and it’s a guide that works! You will not have to worry about messing up your system or wasting your time.

Why build the kernel from source?

If you plan to work on the internals of the Linux kernel or change its behavior, you’ll need to recompile the kernel on your system.

Here are a few specific cases where you’ll need to know how to work with the kernel’s source code:

1. You want to write a really cool ‘Hello world’ program. (Each time you implement your own system call or modify kernel source code, you will need to recompile the kernel to implement the changes)
2. You want to enable experimental features on your kernel that are not enabled by default (or, disable default features that you don’t want)
3. You want to debug kernel source code, enable support for a new piece of hardware, or make modifications to its existing configurations
4. You’re doing a course on Advanced Operating Systems and have no choice but to do this!

In each of the above situations, learning how to build the kernel from source will come in handy.

What you’ll need

A Linux based Operating System (I tried this on Ubuntu 14.04 LTS and the instructions written here are for the same).

You will need to install a few packages before you can get started. Use the following commands for the same.

You will also need up to at least 12 GB of free space on disk, an internet connection to download the source code, and a lot of time (about 45 to 90 minutes).

Downloading and extracting the latest kernel source

Free Download Linux Operating System Source Code In Python

To check your current kernel version, open the terminal and type:

Go to kernel.org and download the latest stable version. At the time of writing this, the latest stable kernel version was 4.7.1, and I will refer to the same in this article. (Note: Try to avoid downloading source from other websites)

Change to the directory where the file was downloaded and extract using:

Change to the extracted linux-4.7.1 directory.

It should contain folders called arch, fs, crypto, etc.

Configuring and Compiling:

Before compiling the kernel, we need to configure which modules are to be included and which ones are to be left out.

There are many ways to go about doing this.

There is no complex procedure to recover files. It will guide throughout the whole recovery process. The smart navigation menu is attractive and has all the features. Easeus data recovery license code.

An easy and straightforward way to do this is to first copy your existing kernel config file and then use ‘menuconfig’ to make changes (if necessary). This is the fastest way to do it and probably, the safest.

This is the part where you could end up removing support for a device driver or do something of the sort which will eventually result in a broken kernel. If you are unsure about making changes, just save and exit.

Note: One of the alternatives to menuconfig is an interactive command line interface accessible using ‘make config’. This helps you configure everything from scratch. Do not use this. You will be asked over a thousand yes/no questions about enabling or disabling modules, which I promise is no fun whatsoever. I did try this out once and somehow managed to mess up the display driver configurations.

gconfig and xconfig are alternate GUI based configuration tools that you could use. I haven’t tried these myself. For this, you’ll need to use make gconfig (or make xconfig) instead of make menuconfig.

Now, we’re all set!

To compile the kernel and its modules, we use the make command.

This is followed by using make modules_install to install the kernel modules.

Finally, we use make install to copy the kernel and the .config file to the /boot folder and to generate the system.map file (which is a symbol table used by the kernel).

List Of Linux Operating Systems

These three steps put together usually take up a lot of time. Use the following command to perform the above tasks:

Note: I have used the -j option to specify the number of cores to be used. This tends to speed up the process considerably. You can use nproc to check the number of processing units available. In my case, it was 4 cores.

Ideally, you shouldn’t need sudo privileges, but, I was running into problems when I didn’t run it with sudo privileges.

Final steps

Once the kernel and its modules are compiled and installed, we want to be using the new kernel the next time we boot up.

For this to happen, we need to use the following command:

Then, use the following command, which automatically looks for the kernels present in the /boot folder and adds them to the grub’s config file.

Now, restart the system and you should see that the new kernel is added to the boot loader entries.

All Linux Operating System Downloads

On following the instructions, assuming there’s enough space available on disk and the current kernel configuration works fine, you shouldn’t encounter any problems. Note that you could always use the old kernel version in case of any problem and try the whole thing again!

The command uname -r should nowshow you the current kernel version being used.

An important note

Linux Operating System

The above steps are needed to build the kernel from source, for the first time. Once, this is done at least once and a new kernel image is ready, making changes and writing our own modules is simple. You will only be using the steps listed under Configuring and Compiling each time something new is to be implemented or configured differently.
